CARPET-BEATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 251,480, dated December 2'?, 1881.

Application led August 19, 1881. (No model.)

To all whom it may concern:

Be it knownthat I, JOHN SPAULDING, a citi zen of the United States, and residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Carpet-Beating Machine, of which the following is a speciflcation. e Myinvention consists, essentially, of a series of carpet-carrying rollers and weighted flexible beaters attached to a roller or shaft; and it furthermore'consists in the peculiar construction and arrangement of the said rollers and beaters and the mechanism for operating the same.

The objects of my invention are, first, to provide a continuous f'eedin g and discharging carpet-beating machine; second, to provide a carpet beating or cleaning machine in which the necessity of sewing together the sections or pieces of the carpet before entering the machine is dispensed with. I accomplish these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is av sectional side view, showing the relative position of the rollers and beatershaft, and represents one beater in the act of delivering a blow. Fig. 2 is a front elevation. Fig. 3 is a detail view of a portion ot' one of the carpetcarrying or feed rollers, showing the grooves or channels therein. Fig. 4 isa sectional end view, showing the gearing by which motion is imparted to the feed-rollers. Fig. 5 is a detail view, showing the cams which operate the feed-rollers. Fig. 6 is a plan view, showing one heater and the manner of att-aching the beaters to their shaft. l'ig. 7 is alongitudinal section through the outer end ofa beater. Fig. S is'a side view ofthe inner end of a beater.

Similar letters are used to designate like parts throughout t-he several views.

A and B represent two carpet-carrying or feed rollers, which are journaled in fixed bean ings, and the one marked B is placed to the rear and somewhat above the. axial line of the roller A. These feed-rollers are provided with a series of circumferen tial grooves or channels, C, the grooves in one roller being aligned with those of the other roller, and are semi-cylindrical in cross-section and receive the endless rope, land, or belt D. These ropes orbelts are placed loosely upon the rollers, and the slack is kept down by the weighted roller or shaft E,whi:h is journaled in bearings F, suspended by a chain, G, from a lever-arm, H, which is pivoted to the framework of the machine, and provided with a weight, I, and by sliding the weight upon the lever-arm the pressure ofthe roller E upon the ropes or belts D maybe regulated. All lateral movement of this roller is prevented by vertical guide-pieces placed on either side of the spindle thereof.

` The beater-shaft J, which is provided with a band-wheel, J, placed above and to the rear of the carpet-carryin g rollers, is provided with a series ofbeaters, K, arranged in longitudinal rows, the beaters in one row corresponding with the spaces between the beatersin the adjoining rows, asis shown in Fig. 6. The beaters are attached to their shaft by means of a bolt, L, which passes through the looped end of the same and enters the eyebolts M M, driven into the beater-shaft.

The beaters K are composed of a strip of leather cut and folded in the form shown, and are weighted upon their outer or striking ends by means of bolts or rivets N, which are provided with washers O, which give it additional weight. The larger head of the bolt or rivet is placed upon the under or striking I'ace of the beater 5 and in order lo prevent the upper head of the rivet from damaging the shaft to which they are attached, I place upon the upper face of the striking portion of the beater a sheet of rubber, P, which is pierced with holes for the passage of the rivets and is scored out to receive the upper washers thereof. By this construction the head of the rivet .is contained within the upper face-line of the rubber, and thereby prevented from coming in contact with the beater-shaft, while the elasticity of the rubber will, in rebounding, give additional force to the blow struck upon the carpet.

To the inner end of the beater I loop over and bolt a short piece of leather, Q, which can be easily replaced when it becomes worn by contact with the boit holding it to the shaft.

In order that the carpetmay be pressed tightly upon the feedrollers and ropes, I provide a series of loose pulleys, It, which may have either a plane or grooved face, placed upon a shaft, S, loosely `journaled in bearings which can be IOO raised and lowered at pleasure by means of the suspending-chains T and chain-wheels T', keyed upon the shaft T2 and operated by the lever T3, as seen in Fig. 2. This shaft is also provided with vertical guide'pieces', which pre vent any lateral movement.-

The pulleysR may be slid along their shaft to suit the width of the carpet being beaten and to regulate the'tension of the same upon the feed-rollers. These pulleys may be keyed directly to the shaft S, or may be heldin place thereon by adjustable collars arranged on either side ot' said pulleys and secured by set screws.

To one end ot' the spindles of the feed-rollers I key the ratchet or gear wheels U U', the teeth of the one U' being inclined in a reverse direction from those of the one marked U. Midway between the two ratchet-wheels I place the bearing V, which supports thejournal V' of the pulley or band wheel V2, around which is placed the driving-belt.

Upon the outer ends of the journal V', I key the cam or tappet wheels W W', the diameter of which is about equal to the vertical distance between the centers of the two feed-rollers. rIlhese cams or tappet-wheels are constructed in the form shown in Fig. 5that is to say, upon the edge ot' the cam-plate a, I rivet the outwardly-projecting band or flange I), which follows the circular but not the radial edge.

The carpets are fed in front ot' the machine and returned at the feeding-point. When teeding carpets into the machine I slide the journal V' in its bearings, so that a cam-wheel will engage with the ratchet-wheel upon the end of thefeed-roller which rst receives the carpet and produce a revolution of the same, motion being communicated to the other roller by means of a connection between the chainwheels X X, keyed upon the opposite ends of the rollers. The cam-wheel may be held to its engagement with the ratchet-wheel by means of a spring or its equivalent. When feeding carpets backward outJ from the machine thejournal V' is moved until the inner face of the iiange b ot' the cam-wheel W', which is curved in a reverse manner from the wheel XV, engages with the ratchet-wheel U' and imparts a reverse motion to the carpet-earryin g rollers. The carpet to be beaten rests mainly upon the endless bands or ropes D, and the beaters are of such a length that the striking or weighted portion thereof will strike the carpet at a point about midway between the feedrollers and cause the greater portion of the dust to be driven downward, while the elasticity of the rope-bed uponwhich the carpet rests will greatly increase the effectiveness of the operation, as the springing back of the ropes after a blow has been struck will impartasecondary blow or shake to the carpet, tending to shake or throw oft' the dust from the upper surface thereof.

Having thus described my invention, what I claim, and desire to `secure by Letters Patent, 1s-

1. In a carpet-beating machine, the combination of the feed-'rollers-A B, grooved in a circumferential manner, and carrying the endless bands or ropes D, which form a rotary feed-bed or support for the carpet, and the revolving beater-shaft J, provided with a series of weighted beaters, K, all constructed, arranged, and operating substantially in the manner herein shown and set forth.

2. In a carpet-beating machine, the combination, with the feed-rollers A B and endless bands or ropes D, of the adj ustably-weighted roller E, for the purpose ot' applying tension to the ropes D, and loosely-journaled shaft S, having a vertical adjustment, and provided with the loosely-hung friction feed wheels or rollers R R, constructed and arranged tol operate substantiallyin the manner herein shown and set forth.

3. In a carpet-beating machine, the combination, with the flexible beaters K, of the rivets N, washers O, and rubber blocks or strips P, for the purpose of imparting weight to the beaters and preventing injury to the beatershaft, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal vthis 6th day ot' August, 1881.
